Fuel Starvation vs Limp Mode
 
Hey guys,

How do you know if you are experiencing fuel starvation vs limp mode. I assume fuel starvation is a quick bog down, like during the duration of a turn and limp mode lasts quite a while. Sound accurate?

limp mode is exactly dat. you can drive your car but at a slow speed..to get you off the highway or get u into a side street.

fuel starve you'll sputter out and no engine start.

kenchan 11-25-2015 05:01 PM

actually i meant to type fuel starve you'll sputter out and engine cut.

I have experienced both. Fuel starvation is when you were taking a long right handed turn and typically you were at one half tank or less. The engine dies and you have to put at least a gallon of gas into it to basically reset it so that it will start again regardless of the actual fuel level.

I have also experienced getting the engine up to 3500 RPM and all the sudden all power is lost until the revs drop down. I have tested this and it occurs in every gear when it is acting up. This is happened to me while driving long-distance and during short trips. If anybody has an explanation for this please let me know.

Does limp mode involve any lights on the dash? I forget.

I know that my car will go into a limp mode (or similar) upon start-up. It will still rev to/above 4000rpm, but very, very slowly. There's no power at all. Generally occurs more in the cooler months.

Then I have to shut it off for about a minute and restart and it's back to normal. No codes, nothing. It's strange.

I don't remember if there is a dash light but a DTC should be thrown. Get an OBD/CAN tool and see which code(s) is present while limp mode is active.

I've got one. I'll have to try it to see if it's throwing any sort of code, but not illuminating a light.

Only code I know of that I have is for the O2 sensors due to the HFC's. And hell, that's not even being thrown at the moment.

limp mode is only for the AT loosers

limp mode is after you have sex.

fuel starve is when you try blast again after sex.

similiar in that you can't perform.

different as in different causes of lack of ability.

could also be because MAF in the intakes are dirty as well...

I've had this happen too and I have no clue what it is, I usually shifted into the next gear and pumped the gas pedal a couple times until I got the engine to rev and go again.
